Show HN: Color-scheme-switcher: auto/manual color scheme toggling in React
A really simple, small package to manage React context around color scheme toggling. Specifically, you can switch color scheme manually or automatically, and if the latter you can follow either the system color scheme or the sun.
I based some of this code heavily on a couple Mantine (https://mantine.dev/) hooks and Suncalc (https://github.com/mourner/suncalc), but modified them to either make them simpler and/or, in Suncalc's case, typed.
This is my first open-source package in a while, so I'd greatly appreciate any constructive suggestions! I have been using some form of this in my own projects and figured, when I added it to the most recent one, I should just extract it into its own project. I'm hoping something small like this will motivate me to do more open-source work because I miss it!

Show HN: Visualize your day as 144 rectangles
It would be fun to see this with local daylight hours mapped to the squares, so I could get a feel for where my consumption is at within "daylight" vs the whole "day"
SunCalc is a good tool for this, if you're interested: https://github.com/mourner/suncalc
(I've used it on a personal project, and the API was a little awkward but the results are good: https://daylight.website/)

How to base things from solar noon, or other inputted target time?
Recently I have made a library doing this for myself. Basicly, I re-wrote this Javascript library in C++ for use with microcontrollers: https://github.com/mourner/suncalc

Does adaptive lighting work the way you expected?
I ignore the sunrise/set properties of the Hue bridge. All the calculations are done on the board itself, so it doesn't need an internet connection to keep working. I used the javascript code here https://github.com/mourner/suncalc as a starting point and translated it to c++ to run on an microcontroller.

Ask HN: What Are You Working On?
Suncalc [1] is the library I use to calculate the position of the sun. Mapzen [2] host public elevation tile data. This blog post [3] is a good overview of the calculations involved.

Show HN: I open-sourced the in-memory PostgreSQL I built at work for E2E tests
I've used pgmem https://github.com/oguimbal/pg-mem for the last couple of years for the same thing.

Ask HN: How do you test SQL?
I was wondering the other day how to classify tests that use a test double like pg-mem, which isn't a mock but isn't the Dockerized test DB either :

How to test nestjs modules?
In my case, I use TypeORM with PostgreSQL, and there's pg-mem to run an instance in memory, it supports most of the common functionality of PostgreSQL but you will need to do some adjustment to your code to be within the limits.

Working with offline data
Postgres in the browser is possible through pg-mem: "pg-mem is an experimental in-memory emulation of a postgres database" but it also suffers from no persistence. If you can persist to a file somewhere then read it in on startup (and if your local data isn't huge) this might work.

Haskell as a first timer - Am I missing something ? Or is something broken ?
Dont get me wrong: I am trying to contribute to opensource as well, so I get that supporting small projects can be demanding. There's nothing wrong in not spending your weekends on OS. But not asking for help, nor specifying that a project is unmaintained, nor even answering issues & pull requests for years feels just wrong.

pg-mem, an in memory postgres DB instance for your unit tests, is now bound to multiple libraries (Knex, Typeorm, Slonik, pg, pg-promise) ... suggestions for the next one ?
Okay, I had a bit of spare time,I've implemented that, and it is now available with [email protected]
